A discus thrower accelerates a discus from rest to a speed of 25.7 m/s by whirling it during 1.20 rev. suppose the discus moves on the arc of a circle 1.04 m in radius.
1. Compute the final angular speed of the discus.
2. Decide the magnitude of the angular acceleration of the discus, assuming it to be constant.
3. Compute the time interval required for the discus to accelerate from rest to 25.7 m/s.
Two blocks are connected by a string. The smooth inclined surface makes an angle of 35 degrees with the horizontal, and the block on the incline has a mass of 5.70 kg. The mass of the hanging block is m= 2.90 kg. Find the direction of the hanging blo..
